This phenomenon is incorporated in a neuron model 
This phenomenon is incorporated in a neuron model derived by Abbott and Kepler that, save for that feature and a time-dependent threshold factor, is a type of Hopfield model. One process that displays this phenomenon exhibits the Barkhausen effect. This phenomenon, displayed by Schmitt triggers and memristors, results, in latching relays, from their bistability. Agar displays a form of this phenomenon in freezing and thawing, though the best known form of this phenomenon can be quantified as remanence and occurs due to a nonlinear relationship between H and B. For 10 points, name this phenomenon, most commonly associated with the way in which objects will retain their dipole alignment after a magnetic field is removed, generally referring to objects and phenomena that display physical memory.
